REVERSIBLE CASEMENT FRAME I I ht INVENTOR Filed Sept. 13. 1929QKMl'Zej/n knee Patented May 19, 1931 Um STATES GEORGE M. KLEINKNECHT,OF FORT LEE, NEW JERSEY REVERSIBLE CASE-MENT FRAME Application filedSeptember 13, 1929. Serial No. 392,335.

The present invention has reference to a versible casement frame ofstock size which is so constructed that the same size sash r storm sashand also the same size screen can be made to-swing either in or out ofthe frame by merely shifting the stops and sub-sills of the frame.

A. further object is the provision of a casement sash frame of standardheights and same height sashes for swinging in or out of the frame aswell as one same size screen for alsoswinging either inwardly oroutwardly so that such frames and sashes can be carried in stock by thedealer to accommodate the trade and eliminating the necessity andexpense and trouble of constructing two different types of frames toaccommodate either outward or inward swing sashes.

Other objects of the invention will appear so from the followingdetailed description which is to be read in connection with theaccompanying drawings.

In the drawings:

Figure 1 is a vertical transverse sectional view through theimprovement, the screen frame being arranged upon the outer face of theframe and the sash upon the inner face thereof. 7

Figure 2 is a similar sectional view but 30 showing the stop andauxiliary sill adjusted to permit of the sashbeing arranged upon theouter face of the frame and the screen upon the inner face thereof.

Figure 3 is a horizontal sectional view approximately on the line 3-3 ofFigure 1.

Figure 4 is a similar sectional view on the line H of Figure 2. v

Referring now to the drawings in detail,

and to Figures 1 to 4: in particular, the sill of the casement frame isindicated by the numeral 8. The sill, on its inner edge is provided withthe usual transverse groove for the reception of the tongue of the stoolof the frame. The side and head jambs of the frame which are of the samepattern are indicated by the numeral 9 and the outer casing of the sideand head casing by numeral 11.

The top and side casing is provided with a groove to receive a filletwhich fillet is on the side and head jambs at approximately the centerthereof. In the groove 10, in the sill 8, there is received the tongue12 of the auxiliary or sub-sill 13, while in the grooves 16 of the sideand head jambs there isreceived the tongue 14 of the vertical and headstop strips 17. The stop strips 17 and the auxiliary sill 13 are of thesame width. Tongues 12 of the auxiliary sill 13 and the tongues 14- ofthe stops 17 are of the same width and the groove 10 in the sill 8 andgroove 16 of the side and head jambs are larger in width than thetongues 12 and 14 by a difference between the thickness of the sash andscreen:

Example :If the sash is 1% and the screen 1 this open space in grooves10 and 16 will be of an inch.

In this manner it will be noted that the stop strips and auxiliary sillmay be shifted or moved laterally in the frame, as disclosed by Figures1 and 3 of the drawings which will permit of the sash 18 being shiftedin the inner face of the frame for in-swinging and the storm sash orscreen frame 19, may be shifted in the outer section. By moving 7 thestop strips and the auxiliary sill to the position disclosed by Figure 2of the drawings, it will be noted that the sash 18 and the screen frame19 may be reversely arranged.

A window which is large in width may be divided by one or more mullionrails 12, which has its opposite faces provided with grooves 21 thatregister with the grooves 16 which are of the same width and depth asthe said groove. I11 these instances, of course, extra auxiliary sillsand extra inner stop strips 17 are provided.

The said strips being formed on their inner or confronting faces withthe tongues 22 that are to receive in the said grooves 21 which saidgrooves are the same as 16 in the side of head jambs.

As disclosed by the drawings the outer face of the auxiliary sill 13 isbeveled and has its inner edge enlarged to form the same with a bead 23,and this bead is covered by a water drip strip 2 1 that is secured tothe outer face of sash frame when sash swings in.

It is obvious that sash of greater thicknesses can be used in thisframe. If thicker 100 sash swing out, theouter edge of. stops 17 andauxiliarysill 13 can be dressed down to ac commodate this thicker size.If thicker sash swings in, inner edge of stops 17 can be dressed downand auxiliary sill 13 remaining the same, bottom rail of sash canberabbeted over bead 23 omitting drip 24. r r r 7 It will be noted thatthe sash height, screen height, storm sash height, all remain the 0 samefor either swinging in or swinging out. 1 Having described theinvention, I claim: A reversible casement frame comprising a main'sillhaving a groove, top and side jambs 1 associated with the sill andhaving grooves therein of equal width with the width of the first namedgroove, an auxiliary sill 10- oated on the main sill, a tongue on theauxiliary sill and extending into the first mentioned groove and'of awidth less than the rowidth ofthe first mentioned groove, stop stripsassociated with the top and side j ambs, tongues on said strips and ofcorresponding width with the width of the first mentioned Y, tongues andextending into the second mena tioned grooves, and sashes of differentthicknesses abutting the strips and auxiliary sill and by shifting thestrips and auxiliary sill laterallythe' sashes may be reversed relativeto each other. 1 r to f In testimony whereof I affix my signature.

GEORGE M. KLEINKNEGHT.
